We fix what's broken, fast, and we don't disappear after the invoice. Priority scheduling available across Fontana and the surrounding zip codes.
No automated menus for emergencies — a real person handles the call.
You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.
Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.
Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Fontana, WI.
We're not interested in being the cheapest quote on the page — we're the crew that answers the phone at 2am when your furnace quits in the middle of a cold snap. Every job we run is backed by full liability coverage and current state licensing, and we keep that documentation available on request for every job, residential or commercial.
Being local matters more than most companies let on. That local knowledge shapes how we diagnose problems — it's the difference between a tech who's guessing and a tech who's seen your exact situation a hundred times before.
Too many homeowners in Fontana have a story about a tech who showed up late, quoted one price, and charged another. That's the gap we built Leonard HVAC to close. We track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Fontana is a small enough community that reputation travels fast.
That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. We keep parts inventory stocked based on what actually fails most often on Fontana's housing stock.
We cover the full range of heating, cooling, and air quality work Fontana properties actually need.
When your Air Conditioning Repair system fails without warning, waiting days for an appointment isn't an option. Our Fontana dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.
If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.
Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Fontana homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.
We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.
Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services multi-zone commercial buildouts across Fontana, with service agreements built around your operating hours.
Property managers working with multiple Fontana locations can set up a standing account so every site gets consistent service history and pricing.
Preventive maintenance is the cheapest repair you'll ever pay for, because it's the one that prevents the bigger bill. Beyond standard tune-ups, we also handle duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Fontana households that want more than just temperature control.
A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.
Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.
Every repair comes with a workmanship warranty explained in plain terms before we leave.
We quote a flat rate before work begins and that number doesn't change once you approve it.

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.
Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.
A system working harder than it should to hit the same temperature shows up directly on your utility bill.
This is one of the warning signs we recommend not waiting on.

"Our AC quit on the hottest weekend of the year and they had a tech out within a couple of hours. The pricing was exactly what they quoted over the phone."
"We've used them for our maintenance plan for two years now and never had a surprise breakdown. You can tell these guys actually know what they're doing."
"They handled the whole install in a single day, exactly like they said they would. Followed up a week later just to check everything was still running fine."
"Our restaurant's rooftop unit went down on a Friday night and they had someone out fast. Now our go-to for every property in the portfolio."
"I appreciated that they didn't try to sell me a bigger unit than I needed. Would use them again without hesitation."
"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. Genuinely relieved to have found a crew that answers when it matters."
Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.
The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.
Simple habits between professional visits also matter. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.
We also service package units common on manufactured and modular homes throughout the Fontana area. If your system was installed by a different company entirely, that's not a problem — we service equipment regardless of who originally put it in, and we'll pull the model and serial information to confirm parts compatibility before any repair begins.
